PUMP.

Specification of Letters Patent.

Application filed August 1, 1911.

To all 11i/om t may concern Be it known that I, RUooLrH CONRADER, acitizen of the United States, residing at Erie, in the county of Erieand State of Pennsylvania, have invented new and useful Improvements inPumps, of which the following is a specication.

This invention relates to pumps and consists in certain improvements inthe construction thereof as will be hereinafter fully described andpointed out in the claims.

Among the objects of the invention is to provide the pump with means formechanically actuating the valve of the pump. This has heretofore beenaccomplished, but is accomplished in accordance with this invention inan improved manner. Means are also provided in connection with themechanically actuated valves for opening the valves of the pump so as todrain the pump for the various purposes for which it is desirable.

The invention also contemplates means whereby the sand settling in thepump may be prevented from packing on the top of the plunger so as toinjure the working surfaces.

Other objects of the invention will appear from the specification andclaims.

The invention is illustrated in the accompanying drawings as follows:

Figure 1 is a central section of a pump on the line 1-1 in Figs. 2, 3,4, 5, 6, 7, 8 and 9, the plunger being lowered preparatory to picking upthe standing valve. Fig. 2 a section on the line 2-2 in Figs. 1, 3, 4,

6, 7, 8, and 9, the plunger being in normal position. Fig. 3 a sectionon the line 3-3 in Fig. 2. Fig. 4 a section on the line 4-4 in Fig. 2.Fig 5 a section on the line 5 5 in Fig. 2. Fig. 6 a section on the line6-6 in Fig. 2. Fig. 7 a section on the line 7-7 in Fig. 2. Fig. S asection on the line 8-8 in Fig. 2. Fig. 9 a section on the line 9--9 inFig. 2.

1 marks the standing valve fitting. This is provided with the bell 2 atits upper end into which the working barrel eXtension 3 is screwed. Theworking barrel extension is connected by a coupling 4 with the workinglbarrel 5. The working barrel 5 is connected by a coupling 6 with a tube7.

The plunger 8 operates in the werking barrel, and as shown is whollymetallic. It is operated by a sucker rod 9. A crown 10 is screwed intothe upper end of the plunger, the plunger being internally screwthreaded of the crown 23.

at 11 for this purpose. A collar 13 is also screwed into the upper endof the plunger and the removable plunger seat 14. is clamped between thecollar 13 and the crown 10. The upper edge of the plunger is beveled,the edge in contact with. the working' barrel being higher than Thecrown 10 is screwed down into the plunger so that the edge 12 formscomplete annulus around the top of the plunger. The webs of the crown(see F ig. 3) are V shaped as indicated at 10 so that any sand that maysettle in the tubing will not lodge around the crown but will pass intothe plunger' and thus may be flushed out of the pump.

The plunger valve 15 has a screw threaded opening at its cent-er intowhich the extension 17 of the sucker rod 9 is screwed. The extension 17is of slightly smaller diameter than the sucker rod 9 forming a shoulder1S which contacts the crown 10 so as to limit the relative movementbetween the sucker rod and the plunger. 0n the downward movement of thesucker rod, the valve is opened through the movement of the sucker rodand the plunger is carried down when the shoulder 1S contacts the crown.

The standing valve has the usual sleeve 19 on which the packing 20 isarranged. The packing 2O is clamped by the base 21 This base has aflange which clamps the removable seat 22 on the top of the sleeve 19.The standing valve check 24 is arranged in the cage and operates uponthe seat 22. It has a screw 'threaded opening' 25 into which the stem 26.is screwed, the stem extending upwardly through an opening 23a in thetop of the crown. The screw is locked in the valve by means of the setscrews 27. rllhe set screws extend outwardly from the check 24 into thespace between the posts 231 in the crown so that they not only lock thescrew in the valve, but also lock the check and stem 2G against turning.

The lower end of the plunger has a strap 28 formed integrally with theplunger, leaving the openings 29 to the plunger'. A screw threadedprojection 30 extends from the lower end of the strap 28 and this iscupped in its lower face forming a gland in which the packing material31 is placed. A flange nut is arranged on the extension 30 and screwedup, against the packing so as to the inner surface.,

create frictional pressure on the stem. As the plunger is reciprocated,the friction on the stem 26 is sufficient to mechanically operate thecheck 2l so that it is opened and closed through the direct action ofthe plunger rather than by the pressure of the liquid as ordinarily.

The upper end of the stem 26 has a shoulder 33 which is of sufficientsize to engage the strapl 28 if the plunger' is withdrawn. In this way,the standing valve may be withdrawn with the plunger, the shouldered eX-tension is of suicient length, and telescopes the plunger sutlicientlyso that in the normal operation of the pump, the shoulder does notcontact the strap 28.

The check 15 is provided with the downwardly extending arms 34 with thecross piece at the bottom. The cross piece has the perforation 36 inwhich is slidingly mounted the nut 3T. The nut has the head 38 adaptedto enga-ge theV arms 3a so as to prevent its turning in the cage thusformed. A spring 89 is tensioned between the top of the nut and thevalve 15, the spring being held in place by a projection l() on the endof the sticker rod at the top and a projection 41 on. the top 0f thenut. rlhe nut 8T is screw threaded so as to engage the screw threads 42on the top of the stem 26. By lowering the plunger below the ordinarystroke of the plunger, the nut 37 can be brought into engagement withthe screw threads 42 at the top of the stem 2G and by turningAV thesucker rod, the nut may be screwed on to the stem Vso that the stem isdirectly connected. l'n order to prevent the bruising of the threads 42as the nut is lowered, thenut is yieldingly mounted, as shown, thespring yielding but still exerting suflicient pressure as-to insure theentry of the screw. The standing valve, of course, could be lifted bythe shoulder but this in` itself would not assure the opening of thepump valves so as to drain the pump and thus facilitate the lifting ofthe parts. The stemy 26 and connected parts are so proportioned thatwhen the nut 37 is fully screwed on to the screw 42, the shoulder 1,8resting on the top of the crown and the tia-nge nut on the top of thestanding valve cage, the check 24 will be lifted from its seat.Observing'liig; 1, the parts are in position tol start the engagement ofthe nut 37 with the screw 42. It will be noted. that the shoulder 18 isin engagement with the crown and the bottom of the plunger with thestanding valve cage. It will also be noted that the nut 37 is liftedslightly but not equal tothe length of the screw 42. By turning thesucker rod 9, kthe nut 37 is screwed down until the head 38contacts thebottom cross piece 35. A further turning of the sucker' rod and thescrew lifts the stem 26 and consequently the check 24C. Often all pump,

that is desired is to iiush the well or flush the pump, and this openingof the two valves, especially in connection with the arrangement of thecrown 10 and edge 12 of the plunger allows the flowing back of the sandand matter that may have accumulated in the tubing in the well. It willbe understood that iuthe normal operation of the most of the sand duringthe activ-e movement of the liquid is carried with it but where thepumping ceases in deep wells the deposit of sand from several thousandfeet in the tubing is what gives trouble.

It will be noted that the yielding screw connection is near the top ofthe plunger.

. there the sand is allowedto pass back into the plunger. it is apt toaccumulate on this connection if it is arranged lower in thej plunger.`Where this happens, the sand clogs the action of the spring and throwsout the yielding feature ofthe connection and the advantages arisingfrom it. ln the present construction this is obviated.

l do not claim broadly in this application the strap 28 formed integralwith theplunger leaving the openings 29, said strap forming a wrenchhold for the plunger nor this structure in connection with a screwthreaded valve seat in the plunger as these features broadli7 consideredform the subject matter of application #582 ,610, filed Sept. 19th,1910.
